In 2021, running was computationally expensive. On a mid-range card like the GTX 1660 Super or RTX 2060, expect a 20-40% performance hit in most games. reshade ray tracing shader rtgi 033 2021

If a light source exists just outside your camera view, RTGI 0.33 cannot bounce light from it. However, within the confines of the visible frame, the shader does an astonishing job of calculating indirect bounce lighting. | GPU Model | Native FPS (1080p) | With RTGI 0
Unlike Nvidia DLSS or native Ray Tracing, which rely on specific hardware cores (RT Cores) inside the GPU, this shader runs on .
